Killifish

Almost any warm water climate in the world has a species of killifish somewhere or fossil record that a species of killifish once existed there. The various species vary in coloration and finnage, and though they are closely related to live-bearing tooth carps, they are egg-laying fish; however, egg-laying in a way unlike any other fish on the planet. Speculation has circulated for years about where these strange colorful short-lived little fish came from or why they evolved everywhere there is warm water. Some theories have been floated around as to where they came from but you should focus on the science today and the facts known about this wonder of nature.
